On this bitterly cold morning, I’m feeling grateful to the people who designed, built, and maintain my little gray Kia Spectra. I bundled up and went out at 4:45 a.m. to (hopefully) start the car and warm it up, and, lo, the engine instantly sprang to life. When I went back out again a few minutes later to drive to the gym, the car felt satisfyingly warm and the motor hummed pleasantly. I said a quiet word of thanks as I drove along the frigid streets in the darkness. I knew there are millions of people living in areas of severe cold who would marvel at the kind of instant and warm transportation that’s available to me. For every lucky person like me who can turn a key and get immediate results, there are thousands who must labor unremittingly in order to stay warm and get where they have to go. As I drove along in my comfortable Kia, simple thankfulness was the strongest feeling I had.
